The next Vancouver PHP User Group meeting will be held on Thursday, July
31, 2003.

The featured speaker is Derick Rethans, discussing the "Ins and Outs of
Xdebug".

Location: ActiveState, 580 Granville Street
Date: Thursday, July 31st
Time: 7pm-8:30pm (doors will open at 6:45pm)

Admission is free, and everyone is welcome to attend this event.

This session teaches you how to detect and debug PHP scripts with the 
free open source tool Xdebug, which is an extension to PHP. The first 
part of the session will cover detecting problems in your scripts by 
showing how Xdebug provides debugging aides in the form of 
stack/function traces, dumps of variables, modified PHP functions. The 
second part will deal with some of the internals of the extension to 
explain how it gathers information from the PHP Engine. In the last part

I will show the remote debugger capabilities of Xdebug, where you can: 
set breakpoints on functions, methods and file/line compabinations; 
watch execution details such as stack frames, per-frame information; run

PHP code to modify the current state of your script and evaluating error

messages. No knowledge of C is required to follow this session, but some

basic knowledge would be beneficial for the second part.
